- Added verify_ajax_nonce() helper method to check both admin and frontend nonces
- Updated ajax_generate_capability_token() to accept frontend nonce
- Updated ajax_get_phone_numbers() to accept frontend nonce
- Updated ajax_get_waiting_calls() to accept frontend nonce
- Updated ajax_accept_next_queue_call() to accept frontend nonce
- Resolves 403 AJAX errors when using shortcode on frontend
The shortcode creates 'twp_frontend_nonce' while admin uses 'twp_ajax_nonce'
Now both are accepted by the AJAX handlers for proper frontend functionality
